Thank you for the questions Abiky.
Do you think we need more decentralized stablecoins?
Yes.
What will happen if centralized stablecoin issuers continue to freeze addresses at will?
It's fucked up. More users/buyers of that cex stablecoin will switch to dex.
Will people lose confidence on centralized stablecoins?
Yes.
Or will this attract institutional investors and serious traders?
If I am the serious (exaggerated) trader then I would prefer the decentralized way.
Obviously, for the reasons you said. I want authority with every move that I will make and not accounts being frozen just because someone on the other end doesn't like how I manage my own money.
Let's just go back to the banking system and do all the KYC if that is the case.
